Description.

Elongate; subconvex; shining; metallic blue, antennae black. Head: vertex punctate, carina present between antennal bases; frons not projecting; depressed between eyes. Antenna: as long as head and pronotum combined; robust; antennomeres 1-3 transverse, subequal in length; 4-10 transverse, subequal in length, each shorter than 3; 11 2 × length of 10, rounded at apex; 1-2 punctate with scattered setae; 3-11 setose. Pronotum: transverse; lateral margin very slightly converging from base to apex, canaliculate; anterior angle rounded, not produced; posterior angle acute; anterior margin emarginate behind head, with small tubercle in notch; disc subconvex; surface with large, variolose punctures, punctures sparse on disc, more dense laterally; basal impression absent; pronotal length 1.0-1.3 mm; pronotal width 1.5-1.9 mm. Scutellum: broadly subpentagonal, acutely pointed at apex; alutaceous. Elytron: lateral margin straight, smooth, margined; apex rounded, finely serrate; sutural angle without tooth; humerus rounded, not produced; slightly constricted behind humerus; regularly but not coarsely punctate-striate, punctures nearly obsolete apically; elytral length 3.5-3.9 mm; elytral width 1.7-2.1 mm. Venter: pro-, meso-, and metasterna punctate; abdominal sterna punctate, each puncture with pale seta; suture between suture 1 and 2 complete; last sternite with apical margin broadly truncate-emarginate me dially . Leg: slender; punctate; tibia with fringe of setae on inner margin of apex. Total length: 4.5-5.6 mm.
